Best Dog-Friendly Hikes in Washington: 10 Trails for You and Your Pup
# Best Dog-Friendly Hikes in Washington: 10 Trails for You and Your Pup
Some of my favorite trail memories involve a dog trotting a few feet ahead, ears up, completely in its element. If you work a desk job all week, a Saturday hike with your dog might be the best reset there is. Washington makes it easy, with thousands of miles of trails across the Cascades, the Columbia River Gorge, and the Puget Sound lowlands. The catch is that not every trail welcomes dogs, and the ones that do come with rules worth knowing before you load up the car.
This guide rounds up the best dog-friendly hikes in Washington for every fitness level, from a one-mile lakeside loop to a leg-burning summit climb. Every trail below allows dogs, and I have included distances, elevation gain, difficulty, parking pass details, and what makes each one worth your weekend.
What Makes a Hike Dog-Friendly?
A trail can be beautiful and still be a bad choice for a dog. When I evaluate dog-friendly hiking trails in Washington state, I look for a few things beyond the scenery.
First, the obvious one: dogs have to be allowed. That sounds simple, but Washington has a patchwork of land managers with different rules, which I will explain in the next section. Second, leash rules matter. Almost every trail on this list requires a leash (usually six feet or shorter), so if your dog pulls like a sled team, pick a shorter, wider trail while you work on training.
Water access is a big plus. Dogs overheat faster than people, and a trail with streams or a lake lets your pup cool off and drink. Shade matters for the same reason, especially on summer afternoons east of the Cascades. Paw-friendly surfaces count too: smooth dirt and forest duff are ideal, while long stretches of sharp scree or hot rock can be rough on paws. Finally, consider crowds and wildlife. A narrow, packed trail with off-leash tension is no fun for a reactive dog, and trails with mountain goats or rattlesnakes demand extra caution.
The Big Rule: Where Dogs Can't Go in Washington
Before you fall in love with a trail, check the land manager. The single most important rule for hiking with dogs in Washington is this: dogs are not allowed on trails inside the state's three national parks (Mount Rainier, Olympic, and North Cascades). National Park Service policy bans pets on trails, in the backcountry, and on most park beaches. You will see the most spectacular alpine meadows in the state at places like Paradise, but your dog has to sit those out.
The good news is that most other public land welcomes leashed dogs:
- Washington State Parks allow leashed dogs on trails and in campgrounds. You will need a Discover Pass for parking.
- National forests (Mount Baker-Snoqualmie, Gifford Pinchot, Okanogan-Wenatchee, and others) generally allow leashed dogs on trails. Many trailheads require a Northwest Forest Pass or America the Beautiful pass.
- Washington DNR land (places like Rattlesnake Ledge and Mount Si) allows leashed dogs. A Discover Pass is required at developed trailheads.
- Columbia River Gorge National Scenic Area trails generally allow leashed dogs, though some areas have seasonal restrictions.
One more thing: always check the Washington Trails Association (wta.org) trip reports before you go. Closures, snow, washed-out bridges, and temporary dog restrictions show up there first.

*Pass requirements change; check the WTA page for each trail before you go.
1. Rattlesnake Ledge
If you only do one dog-friendly hike near Seattle, make it this one. Rattlesnake Ledge is a 4-mile round trip with 1,160 feet of steady climbing through second-growth forest, ending at rocky ledges with sweeping views over Rattlesnake Lake and the Snoqualmie Valley. The trail is wide, well-graded, and easy to follow, which makes leash management simple. Dogs must stay leashed, and you should keep them back from the ledge edges at the top. There is no parking pass required, which is rare this close to the city. Go on a weekday morning or arrive early on weekends, because the small lot fills fast.
2. Franklin Falls
Franklin Falls is the perfect first hike for a new dog owner or a puppy building trail fitness. At just 2 miles round trip with 400 feet of gain, it follows the South Fork Snoqualmie River through old-growth cedar to a pretty 70-foot waterfall. The trail is gentle enough for kids and older dogs, and the river gives your pup plenty of chances to splash and drink. A Northwest Forest Pass is required at the trailhead. In winter the road to the trailhead sometimes closes, adding extra mileage, so check WTA trip reports in the off season.
3. Twin Falls (Olallie State Park)
Twin Falls packs a lot of drama into 2.6 miles. The trail crosses wooden bridges bolted into a rocky canyon above the South Fork Snoqualmie River, with two powerful waterfalls as the payoff. It is shady, mossy, and classic Pacific Northwest, which means it stays cooler on warm days. Keep your dog leashed and close on the bridges, and watch for slick boardwalks after rain. You will need a Discover Pass. This is a state park, so dogs are welcome on leash throughout.
4. Wallace Falls
Wallace Falls is one of Washington's most popular waterfall hikes, and it earns the crowds. The Woody Trail climbs about 5.5 miles round trip with 1,300 feet of gain past three distinct waterfalls: Lower, Middle, and Upper. If your dog (or you) runs out of steam, the Lower Falls viewpoint is an easy turnaround that still feels rewarding. The Middle Falls overlook has the best views, out over the Skykomish Valley to the Olympics. A Discover Pass is required, and the lot fills by mid-morning on nice weekends. Dogs must be leashed.
5. Little Si
Little Si is the scrappy little sibling of Mount Si, and it is a better pick for most dogs. The 3.7-mile round trip gains 1,300 feet to a rocky summit with big views of its famous neighbor. The trail is steep in spots but short enough to be a satisfying half-day outing. There are a few scramble-y rock sections near the top where you will want a short leash and a steady hand. A Discover Pass is required. This is a great training hike if you are building toward bigger dog-friendly summits.
6. Lake 22
Lake 22 is the prettiest moderate hike on this list. The 5.4-mile round trip climbs 1,350 feet past waterfalls and giant old-growth cedars to a serene subalpine lake ringed by peaks. Dogs are allowed on leash, and the lake is a great swimming spot for water-loving pups in summer. The trail can be rocky and rooty in places, so it is a good workout without being brutal. A Northwest Forest Pass is required. Note that this trail sits in the Mount Baker-Snoqualmie National Forest, not inside a national park, which is exactly why your dog can come along.
7. Gold Creek Pond
Not every great dog hike needs to be a workout. Gold Creek Pond is a flat, 1.2-mile boardwalk loop around a glassy mountain lake at Hyak, near Snoqualmie Pass. It is wheelchair and stroller accessible, which also makes it ideal for senior dogs, puppies, or a low-key evening walk after work. The old-growth cedar and the reflections on the water are genuinely beautiful. Dogs must stay leashed. Check WTA for current parking pass requirements before you go, since this is a busy federal recreation site.
8. Dog Mountain
With a name like that, it had to make the list. Dog Mountain in the Columbia River Gorge is a 6-mile round trip with a stiff 2,800 feet of elevation gain, and it is the hardest hike here. The reward is enormous: in spring, the slopes explode with yellow balsamroot wildflowers, and the summit views stretch across the Gorge to Mount Hood. Dogs must be leashed. Important: a permit is required to hike Dog Mountain on spring weekends (typically April through June) to manage crowds, so plan ahead. Bring more water than you think you need; the exposed upper trail gets hot.
9. High Rock Lookout
Here is the workaround for the national park dog ban. High Rock Lookout sits just outside Mount Rainier National Park, so dogs are allowed on leash, and the payoff is a historic fire lookout with a straight-on view of Mount Rainier. The trail is 3.2 miles round trip with 1,365 feet of gain, short but steep. The lookout itself is small and perched on rock, so keep your dog leashed and under control at the top. The access road is rough and often requires high clearance, and snow lingers into summer, so this is best as a late-summer or early-fall adventure. Check WTA trip reports for road conditions.
10. Mount Si
For fit dogs and experienced hikers, Mount Si is the classic Seattle-area challenge: 8 miles round trip with 3,150 feet of gain to a summit with huge views over the Snoqualmie Valley. The trail is relentless but non-technical, and there is water along parts of the route. This is a serious half-day to full-day effort, so build up to it with the shorter hikes on this list first. A Discover Pass is required, and the main lot fills extremely early on weekends (there is an overflow lot, but it fills too). Keep your dog leashed; this is a busy trail with lots of passing.
Trail Etiquette and Safety for Hiking With Dogs
A well-behaved dog keeps trails open for all dogs. A few non-negotiables:
- Leash up, every time. Even if your dog is friendly, other hikers, horses, and wildlife deserve space. Most Washington trails require leashes of six feet or less.
- Yield the trail. Step aside with your dog for uphill hikers, horses, and mountain bikers. Keep your dog on the downhill side, away from drop-offs.
- Pack out waste. Dog poop does not biodegrade harmlessly on busy trails. Bag it and carry it out. Leaving bagged poop "to grab on the way back" counts as littering.
- Watch the heat. Dogs overheat much faster than humans. Hike early in summer, bring extra water, and learn the signs of heat stress: heavy panting, drooling, glazed eyes, and stumbling. East-side trails like Dog Mountain can be brutally hot by midday.
- Mind the wildlife. Mountain goats roam trails like High Rock and Mount Ellinor and can be aggressive; give them at least 50 yards. East of the Cascades, watch for rattlesnakes on sunny trails and check your dog for ticks afterward.
- Protect the paws. Hot rock, sharp scree, and snow can all injure paw pads. If your dog starts limping or licking its paws obsessively, stop and check. Booties are worth packing on rough or snowy routes.

FAQs About Dog-Friendly Hiking in Washington
Are dogs allowed in Washington's national parks? No, not on trails. Dogs are prohibited on trails, in the backcountry, and on most beaches in Mount Rainier, Olympic, and North Cascades National Parks. They are generally allowed in parking lots, campgrounds, and along roads, but not on the trails themselves. Stick to state parks, national forests, and DNR land for hiking with your dog.
Do dogs have to be on a leash on Washington trails? Almost always, yes. State parks, DNR land, and most national forest trails require leashes, typically six feet or shorter. A few trails have designated off-leash areas or seasons (Coyote Wall in the Gorge has an off-leash season), but these are the exception. When in doubt, leash up.
What is the easiest dog-friendly hike near Seattle? Gold Creek Pond (1.2-mile flat loop) and Franklin Falls (2 miles, 400 feet of gain) are the gentlest options on this list. Both are doable for puppies, senior dogs, and brand-new hikers. Rattlesnake Ledge is the best easy-moderate step up.
Can I take my dog hiking in the snow? Yes, with preparation. Stick to short, familiar trails at first, watch for signs your dog is getting cold (shivering, lifting paws, whining), and consider booties and a dog jacket for deep snow. Some sno-parks require a Sno-Park permit in winter. Avoid avalanche terrain entirely.
How do I keep my dog safe from ticks and rattlesnakes? Use a vet-approved tick preventative, check your dog's ears, belly, and paws after every hike east of the Cascades, and keep your dog on the trail and leashed in rattlesnake country (sunny, rocky slopes on the east side). If you suspect a snakebite, get to a vet immediately; do not wait for symptoms.
What should I do if my dog meets a mountain goat or bear? Keep your dog leashed and close, stay calm, and give the animal plenty of space (at least 50 yards for goats). Never let your dog chase wildlife. For bears, make noise, make yourself look big, and back away slowly. An encounter is a good reminder of why the leash rule exists.
Get Out There This Weekend
Washington is one of the best states in the country for hiking with dogs, as long as you know which land you are on and follow the rules. Start with an easy one like Franklin Falls or Twin Falls, work up to Rattlesnake Ledge or Lake 22, and save Dog Mountain or Mount Si for when you and your pup are both trail-fit. Check WTA trip reports the night before, pack the checklist above, and leave the trails cleaner than you found them. Your dog will thank you with the best nap of its life on the drive home.
